Photocatalytic Degradation of Direct Blue 14 by Polyaniline/CdS Nanocomposite

Polyaniline/cadmium sulfide (PANI/CdS) nanocomposite photocatalyst was used to degrade of Direct Blue 14 (DB 14). Response surface methodology (RSM) was applied to design the experiment, generate a model and optimize the process. Under optimum conditions (initial concentration of DB 14= 5 mg L-1, catalyst concentration= 0.4 g L-1, pH= 3.5, time= 55 min), dye removal efficiency reached to up 83.65.5%.
